Description

Technical Field

[0001] This utility model relates to the field of fabric production, and in particular to a high-precision embossing machine. Background Technology

[0002] While traditional embossing equipment can accomplish basic embossing tasks to a certain extent, its shortcomings are becoming increasingly apparent as industries demand more stringent product quality. The most prominent issue is the difficulty in precisely controlling the roller spacing. In actual production, materials of varying thicknesses need to be processed frequently. Older embossing machines often rely on manual adjustment of the roller spacing, which is not only tedious and time-consuming but also prone to errors due to human judgment. This not only affects production efficiency but also results in inconsistent embossing depth, making it impossible to ensure product consistency and increasing the scrap rate. Even more challenging is the inherent unevenness of common embossed materials like fabrics, whose thickness varies throughout. Traditional embossing machines struggle to flexibly adjust pressure to address this uneven thickness, leading to uneven pressure application and ultimately producing embossed products with rough textures and poor precision. For example, the patent with publication number CN203543219U discloses a bonding embossing machine. This device still has the following shortcomings in the field of fabric production: when encountering situations where the thickness of the fabric itself is uneven during embossing, it is difficult to ensure the consistency of the pressure during embossing, resulting in poor embossing accuracy. Utility Model Content

Through a carefully designed adjustment mechanism, the spacing between the rollers can be precisely controlled to adapt to the embossing production of fabrics of different thicknesses. Furthermore, by setting a constant pressure mechanism, a constant pressure is ensured to participate in the embossing process, which can effectively solve the problem of uneven embossing depth and inaccurate texture caused by the unevenness of the fabric itself during embossing. This ensures the accuracy of the embossing.

Detailed Implementation

[0025] The following will refer to the appendix in the example of this utility model. Figure 1 - Appendix Figure 8 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This utility model provides a technical solution: a high-precision embossing machine, including a frame (1), an embossing mechanism 2 fixed inside the frame 1, and an adjustment mechanism 3 fixed to the upper end of the embossing mechanism 2; the frame 1 serves as the supporting structure of the entire high-precision embossing machine, bearing the embossing mechanism 2, the adjustment mechanism 3, and other components, providing a stable installation foundation for each component, ensuring that the entire equipment remains stable during operation and will not shake or shift due to the force generated during operation, thereby ensuring that the embossing operation can be carried out accurately and smoothly. The embossing mechanism 2 is the core part that directly performs embossing operations on the fabric, allowing the fabric to pass between two rollers, and forming the required texture on the fabric surface under pressure. It works in conjunction with the adjustment mechanism 3 to adjust the working state according to different fabric thicknesses and other conditions to achieve precise embossing. The adjustment mechanism 3 can precisely control the spacing between the rollers to adapt to the embossing production needs of fabrics of different thicknesses. Through the coordinated operation of its internal components, the embossing pressure and related parameters can be adjusted to ensure that even when the fabric itself is uneven or the thickness varies in different areas, the embossing depth remains uniform and the texture is accurate.

[0027] The adjustment mechanism 3 includes a slide rail 301 fixed on the frame 1, a sliding bearing seat 302 fixed inside the slide rail 301, a fixing nut 303 fixed on the upper end of the sliding bearing seat 302, a constant pressure mechanism 304 threadedly connected to the first fixing nut 303, a fixing plate 305 fixed on the upper end of the constant pressure mechanism 304, and a hydraulic cylinder 306 fixed on the upper end of the fixing plate 305. The slide rail 301 provides guidance and limiting for the sliding bearing seat 302, enabling it to slide smoothly along a specific direction, thereby driving other connected components to make corresponding position adjustments, ensuring the directionality and accuracy of the adjustment process. The sliding bearing seat 302 connects to the roller, allowing it to slide up and down. The fixing nut 303 connects the sliding bearing seat 302 to the upper constant pressure mechanism 304. The constant pressure mechanism 304 ensures constant pressure during the embossing process, overcoming thickness differences caused by uneven fabric. This ensures relatively stable pressure throughout the fabric during embossing, preventing uneven embossing depth and inaccurate texture due to pressure fluctuations, thus ensuring consistent embossing quality. It significantly improves the uniformity and accuracy of embossing. Regardless of the fabric's texture or thickness, constant pressure ensures an ideal embossing effect, effectively improving product quality and conformity. The fixing plate 305 primarily serves to fix and connect the constant pressure mechanism 304 to the upper hydraulic cylinder 306, making them a unified structure. This ensures smooth force transmission and stable relative positions of the components during operation. The hydraulic cylinder 306 connects to the constant pressure mechanism 304, using hydraulic power to adjust the distance between the two rollers to a suitable level before embossing.

[0028] The constant pressure mechanism 304 includes a housing 3041 fixed to the lower end of the hydraulic cylinder 306, a sealing ring 3042 fixed to the lower end of the housing 3041, a fixing ring 3043 fixed to the outside of the sealing ring 3042, a connecting rod 3044 fixed to the inside of the sealing ring 3042, a piston 3045 fixed to the top of the connecting rod 3044, a second fixing nut 3046 threaded to the upper end of the piston 3045, a piezoelectric mechanism 3047 installed on the upper end of the piston 3045, an electromagnet 3049 fixed to the top of the housing 3041, and a current limiting mechanism 3048 fixed to the upper end of the housing 3041. The housing 3041 serves to protect the internal components, enclosing the sealing ring 3042, connecting rod 3044, piston 3045, and other components inside, forming a relatively closed and stable space to prevent external impurities from interfering with the normal operation of the internal components. It also provides an overall framework structure for the installation and coordinated operation of the various components. The sealing ring 3042 isolates the external environment, ensuring a stable pressure environment inside the constant pressure mechanism 304. It is a key sealing component for maintaining constant pressure, preventing air from entering the housing 301 and reducing the rebound effect of the piston 3045. The fixing ring 3043 fixes and supports the sealing ring 3042, ensuring that the sealing ring 3042 remains in the correct position during operation, maintaining a good sealing state. Together with the sealing ring 3042, it ensures the sealing performance and stability of the constant pressure mechanism 304. The connecting rod 3044 connects the sliding bearing seat 302 and the piston 3045, transmitting force and motion. The piston 3045 is a key motion and pressure regulating component in the constant pressure mechanism 304. Inside the housing 3041, its up-and-down movement compresses the piezoelectric mechanism 3047 to generate current, thereby adjusting the magnetic strength of the electromagnet 3049. This, in turn, controls the flow limiting mechanism 3048 to regulate the speed of hydraulic oil flowing through it, ensuring constant pressure. The second fixing nut 3046 is used to fix the piston 3045 on the connecting rod 3044. The piezoelectric mechanism 3047 can generate current according to pressure changes, thereby adjusting the magnetic field strength of the electromagnet 3049. The electromagnet 3049 uses the electromagnetic principle to generate a magnetic field by energizing it to adjust the speed of the hydraulic oil passing through the flow limiting mechanism 3048, thereby quickly adjusting the pressure of the roller and maintaining a constant pressure on the fabric.

[0029] A first sealing ring 30410 is fixed to the outer end face of piston 3045, and a second sealing ring 30411 is fixed to the inner side of piston 3045. The first sealing ring 30410 is installed on the outer end face of piston 3045 and is mainly used to seal the gap between piston 3045 and the inner wall of housing 3041 to prevent hydraulic oil from leaking from this part, ensuring a stable pressure environment inside constant pressure mechanism 304 and maintaining good sealing performance. The second sealing ring 30411 prevents hydraulic oil from flowing out from the gap between piston 3045 and connecting rod 3044.

[0030] The piezoelectric mechanism 3047 includes a first spring 30412 fixed to the upper end of the piston 3045 and a piezoelectric ceramic 30413 mounted on the upper end of the first spring 30412. The first spring 30412 serves as a support and buffer, and can buffer part of the impact force when the piezoelectric ceramic 30413 is subjected to pressure or other external forces, thus protecting the piezoelectric ceramic 30413. On the other hand, in cooperation with the piezoelectric ceramic 30413, the piezoelectric ceramic 30413 can generate current of different magnitudes according to the force of the first spring 30412.

[0031] The current limiting mechanism 3048 includes a flow plate 30414 fixed to the upper end of the piezoelectric ceramic 30413, a current limiting plate 30415 installed on the upper end of the flow plate 30414, a current limiting piston 30416 fixed to the upper end of the current limiting plate 30415, a piston housing 30417 installed on the outside of the current limiting piston 30416, and a second spring 30418 installed inside the piston housing 30417. The flow plate 30414 cooperates with the current limiting plate 30415 to adjust the speed of hydraulic oil flowing through the flow plate 30414. The electromagnet 3049 attracts the current limiting piston 30416 to move inside the piston housing 30417, thereby adjusting the distance the current limiting plate 30415 is lifted and controlling the hydraulic oil flow rate. The second spring 30418 is used to return the current limiting piston 30416 to its original position when the electromagnet 3049 is not energized.

[0032] The flow plate 30414 is provided with a through hole 30419; the through hole 30419 is used for the passage of hydraulic oil.

[0033] A conical plunger 30420 is provided at the lower end of the flow restrictor 30415; the flow rate of hydraulic oil is controlled by controlling the distance of the plunger 30420 into the through hole 30419.

[0034] Working principle:

[0035] The fabric is passed between the two rollers in the embossing mechanism 2. The hydraulic cylinder 306 adjusts the distance between the rollers to a suitable level. When the thickness of the fabric area increases, the upper roller is squeezed, and the squeezing connecting rod 3044 drives the piston 3045 to move upward, squeezing the first spring 30412 in the piezoelectric mechanism 3047. This squeezes the piezoelectric ceramic 30413 to generate current. The current flows into the electromagnet 3049 to generate a magnetic field, attracting the current-limiting piston 30416 to move upward. The plunger 30420 on the current-limiting plate 30415 moves upward away from the through hole 30419, increasing the flow rate of the hydraulic oil. This reduces the resistance of the upper roller's movement, ensuring that the pressure on the fabric remains constant. When the thickness of the fabric decreases, the first spring 30412 and the second spring 30418 rebound, causing the upper roller to return to its original position.
